a cylinder has a T.S.A. of 462sq cm.its C.S.A.is 1/3of the T.S.A find the volume of the cylinder.?

Question

please mention all the steps

Answer 1

TSA=2pirh+2pir^2=462
CSA=2pirh=(1/3)*462
=462/3=154
subtracting 2 pir^2=308
r^2=308*7/44
r=sq.rt of 49=7
substituting 2*22/7*7*h=154
h=308/44=7/2
volume=pir^2h=(22/7)*49*7/2
=539 cc

Answer 2

hi christine...i dont know what TSA or CSA means...could you please elaborate on them, then i could help you, thanks
